minimum of one instruction <strong>and</strong> a maximum of three instructions are displayed on<br />

each line. The storage key is displayed on the first line of a request <strong>and</strong> at every<br />

page boundary.<br />

Response 5:<br />

Xhexloc stringhexadecimaldata [key][Lhexloc]<br />

is the response you receive with the S option. The storage key is displayed on the<br />

first line of a request <strong>and</strong> at every page boundary.<br />

Response 6:<br />

Xhexloc1 TO hexloc2 KEY = kk<br />

is the response you receive with the K option. The oper<strong>and</strong>s hexloc1 <strong>and</strong> hexloc2<br />

are storage locations, <strong>and</strong> kk is the associated storage key. A response is sent for<br />

every contiguous address range that has unique storage keys <strong>and</strong> whenever a<br />

segment boundary is crossed.<br />

Response 7:<br />

The PSW is used to resolve a logical address. A PSW that is not valid causes the<br />

current request to be rejected <strong>and</strong> processing to continue with the next request (if<br />

any) on the comm<strong>and</strong> line. In all cases, a reset PSW (all-zero) is accepted. The<br />

rejected oper<strong>and</strong>s are displayed along with a response indicating that the PSW is<br />

not valid. The response is:<br />

addr1 is not addressable because of an nonvalid PSW.<br />

The oper<strong>and</strong> addr1 is the rejected oper<strong>and</strong> or oper<strong>and</strong>s; it specifies an address<br />

space <strong>and</strong> a storage location within that address space.<br />

Response 8:<br />

The dynamic-address translation (DAT) process uses the segment table designator<br />

(ASCE) to convert a third-level address to a second-level address (storage that<br />

appears real to your virtual machine). The translation process may generate one of<br />

several exceptions, identifying why one or more pages of storage are not<br />

addressable. A range of rejected storage addresses is displayed along with a<br />

response indicating the nature of the exception condition. The responses are:<br />

Xhexloc1 to hexloc2 nonaddressable storage<br />

- protection exception<br />

Xhexloc1 to hexloc2 nonaddressable storage<br />

- addressing exception<br />

Xhexloc1 to hexloc2 nonaddressable storage<br />

- segment translation exception<br />

Xhexloc1 to hexloc2 nonaddressable storage<br />

- page translation exception<br />

Xhexloc1 to hexloc2 nonaddressable storage<br />

- translation specification exception<br />

xhexloc1 to hexloc2 nonaddressable storage<br />

- ASCE type exception<br />

xhexloc1 to hexloc2 nonaddressable storage<br />

- region-first-translation exception<br />

xhexloc1 to hexloc2 nonaddressable storage<br />

- region-second-translation exception<br />

xhexloc1 to hexloc2 nonaddressable storage<br />

- region-third-translation exception<br />
